Documents and imports
PDFs, DRM-free EPUBs, text and selected images are copied into the app's own library. Text extraction, PDF previews, cover extraction and optical character recognition run locally. Camera scanning requests camera access only for a scan. The app retains source locations so you can inspect the original passage. Library files and imported originals are excluded from device backups in the current build.
Article links
Fetching an article is an explicit action. The app requests the URL and follows permitted redirects through an ephemeral, cookie-free session. The website and any redirect destination receive the requested URL and normal network information, including your IP address. Imported page text is extracted without running website scripts or loading page subresources. Pasting a URL alone does not fetch it.
Cards and learning history
Cards, exact supporting quotes and review schedules are saved locally. Model-generated cards are drafts for your review, with source validation before saving. Deleting a source also removes its linked cards and copied original. Study does not share a library with Reader or other Embasis apps.
On-device models
Apple Intelligence, LFM2.5-1.2B-Instruct QAD and Gemma 4 are separate model options. Availability depends on the device, operating system, installed assets and the task. Generation runs locally with no automatic cloud fallback. Downloading a model contacts its hosting provider, including Hugging Face, with ordinary network information such as your IP address and the asset requested; it does not send your documents or conversation. Downloads are explicit and integrity checked. Apple may download its own system assets.
Storage and control
The app has no account, advertising or app-managed cloud synchronization. Saved content and preferences belong to this app's local storage. You can remove saved items in the app; deleting the app removes its app data, subject to operating-system backups. Manage any retained backups separately. Exporting or sharing creates a copy with the recipient you choose. This policy describes the current development build; features may change before release.
Third-party services
Third-party downloads, websites, and Apple platform services have their own privacy practices. Their requests may include ordinary network information such as your IP address and the requested resource. See Apple's explanation of device backups.
Changes to this policy
Features and platform availability can change between releases. The current version of this policy is published on this page.
